To keep in theme with the hack-o-rama, even though I think it's a
lousy way to do this...
$str = substr($str, 1, -1); //chop off lead/end square brackets
$layers = explode('][', $str);
$str_array = array();
$layers = array_reverse($layers);
foreach($layers as $layer){
$str_array[] = $layer;
$str_array = array($str_array);
//or something like that...
}

I think you mean this one:
http://php.net/eval
:-)
Though the other suggestion might be more suitable to what you are doing:
http://php.net/create_function
You may want to post the Big Picture of what you are doing and how you
got that string in the first place, because 99 times out of 100, when
people use eval, there's an easier way to do it.
